Boana xerophylla is a species of frog in the family Hylidae. It is found in northern Brazil, French Guiana, Guyana, Suriname, and Venezuela south of the Orinoco. Boana xerophylla was described in 1841 as Hyla xerophylla. However, for decades in the 1900s, it was regarded as a synonym of Boana crepitans, until it was resurrected as a separate species in 2017. In 2021, the Boana xerophylla populations north of the Orinoco river were separated as a new species, Boana platanera. A population from Suriname has sometimes been called Boana fuentei, but it's currently classified as a synonym of Boana xerophylla.
The dorsal coloration of Boana xerophylla ranges from dark brown to green. It's average snout–vent length is 49.69 millimetres (1.96 in). Wikipedia →

Likely
About 60% of wildlife watchers report a Drylands Tree Frog sighting in Brownsberg Nature Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 18 amphibians we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
November and December
In those months about 80% of wildlife watchers report a Drylands Tree Frog in Brownsberg Nature Park on a given day, against about 10% in February, April and July, the lowest months. June and August–September have too few records to rate.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Drylands Tree Frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate Drylands Tree Frog sightings: about 60% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Drylands Tree Frog is recorded against all the amphibians logged in Brownsberg Nature Park (22 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
